Answer:
if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.
----------
Note: sin and cos are complementary functions....
sin(x) = cos (90-x)
-------------------
Your Problem:
sin(x-3) = cos(90-(x-3))
Equation:
90-[x-3] = 2x+6
90-x+3 = 2x+6
3x = 93-6
x = 31-2
x = 29

MAKE MY ANSWER BRILLINEST PLEASE:)
Step-by-step explanation:
LET:
j = the points that Jessica scored
t = the points that Tina scored
Jessica scored 147 more points than Tina:
j = t + 1497
Together, Bradley and Harner scored 1601 points:
j + t = 1601
by solving the system of equations:
j = t + 147
j + t = 1601
we find
j = 856 points
t = 707 points
Jessica Bradley scored 856 point.
Tina Harner scored 707 points.
Well, as far as I can tell, the mean (average) is the best representation of the data because there is no outlier (a number a lot higher or lower than the rest of the numbers that throws the data off).
Answer:
C) Tom did not distribute to both terms in parentheses.
Step-by-step explanation:
Addition within a paranthesis has a distributive property to the multiplier outside the paranthesis. Ignoring this will lead to a wrong value for the operation.
